Specifically tailored to reliably deliver up to 14 Mbps over the difficult powerline communication environment, PowerPacket combats deep attenuation notches, noises sources, and multi-path fading by allocating usable frequencies according to the signal to noise ratio (SNR). Synchronization is achieved in low SNR channels without the use of pilot carriers.

The MAC implements a CSMA/CA scheme with prioritization and automatic repeat request (ARQ) for reliable delivery of Ethernet packets via packet encapsulation. Built-in Quality of Service (QoS) features provide the necessary bandwidth for multimedia payloads including voice, data, audio, and video. Prioritized random access along with segment bursting minimizes the demands on the receiver resources and maximizes the throughput of the network while still providing excellent latency response and jitter performance.

PowerPacket’s contention-free access capability extends this concept of segment bursting to allow the transmission of multiple frames over the powerline without relinquishing the control of the medium. Utilizing contention-free access, a single station may act as a controller for the entire network.

System designers have the option of embedding PowerPacket-specific control information within the packet stream for optimal control and performance or may choose to provide this information via the separate E² PROM interface. Providing this configuration and control information through a separate E² PROM interface allows the system designer to leverage standard Ethernet drivers.

Intellon offers a complete solution for powerline communication applications by providing complete reference designs, data sheets, reference manuals and device driver source code along with a strong technical support staff to ensure your time-to-market requirements are met.
